使用 WSL 2 的 VS Code 中的 Jupyter Notebooks 不起作用

Question

I want to use Jupyter Notebooks inside VS Code running within WSL 2. Regular Python works within WSL without a problem, that means the base conda enviroment is connected and I can run .py files. Moreover, I'm able to run the command jupyter notebook which will start the notebook server within WSL exposing the localhost to the Windows system.

However, I want to test the new Jupyter Notebook feature within VS Code, which is not working for me; VS Code shows: Jupyter Server: No Kernel and Python: Not Started (see screenshot below).

My testing machine is:

• WSL 2 (using Pengwin distribution) on Windows 20H1 (19041.21)
• VS Code 1.41 (having the Python extension installed)
• Anaconda

What I did:

1. Open WSL
2. Open VS Code in my target directory ( code . )
3. Create a new Notebook file from the command palette Python: Create New Blank Jupyter Notebook
4. Create dummy print("test")
5. Run Cell will trigger the warning:

Is there anything I'm missing?

Answer 1

The VS Code insiders actually works out of box with Jupyter notebooks. Just remember to run code-insiders . instead of code . .

Another solution would be, according to this website , start the VS Code in windows, then use WSL 2 as a remote server.

Answer 2

The code installation on wsl2 needs a restart to work properly, I was told by a notification, and in the question's comments you may see people experiencing the same issue(' it's working now. not sure why'). So before looking upon any elaborate solution, just restart code.
